2. Začínáme

2.1. Instalace baterie

The Sharp EL501X2BWH calculator operates on two LR44 batteries (included). To install or replace batteries:

1. Ujistěte se, že je kalkulačka vypnutá.
2. Najděte kryt přihrádky na baterie na zadní straně kalkulačky.
3. Remove the cover using a small screwdriver.
4. Insert two new LR44 batteries, observing the correct polarity (+/-).
5. Bezpečně nasaďte kryt prostoru pro baterie.

Poznámka: Vždy používejte nové baterie a staré baterie zlikvidujte zodpovědně.

2.2. Zapnutí a vypnutí

• Chcete-li zapnout kalkulačku, stiskněte tlačítko ON/C tlačítko.
• To turn off the calculator, press the 2. F tlačítko následované VYPNUTO tlačítko.

2.3. Zobrazit přesview

The calculator features a 10-digit, 1-line LCD display. Indicators for various modes (e.g., DEG, RAD, GRAD, CPLX, STAT) will appear on the display to show the current calculator state.

3. Základní operace

3.1. Arithmetic Calculations

Perform basic arithmetic operations using the number keys and the +, -, ×a ÷ klíče. lis = pro zobrazení výsledku.

• Exampten: Pro výpočet 15 + 7: Stiskněte 1 5 + 7 =. Na displeji se zobrazí 22.

3.2. Clear Functions

• Stiskněte CE to clear the last entered number or operation.
• Stiskněte ON/C to clear all entries and reset the calculator to its initial state (except memory).

4. Vědecké funkce

The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the 2. F key before the desired function key.

4.1. Trigonometric Functions

Použití hřích, cos, opálení for standard trigonometric calculations. Their inverse functions (hřích^-1, cos^-1, opálení^-1) are accessed via 2. F.

The angle unit can be changed using the DRG klíč. Stiskněte DRG repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).

4.2. Logarithmic and Exponential Functions

• Logarithms: Použití log (základ 10) a ln (přirozený logaritmus).
• Exponentials: Použití 10^x (přístupné přes 2. F a log) a e^x (přístupné přes 2. F a ln).

4.3. Powers and Roots

• Náměstí: Použití x².
• Odmocnina: Použití √ (přístupné přes 2. F a x²).
• Obecná síla: Použití y^x.
• Reciprocal: Použití 1/x (přístupné přes 2. F a y^x).

4.4. Factorials

Calculate factorials using the n! function (accessed via 2. F a CPLX).

5. Pokročilé funkce

5.1. N-Base Calculations (HEX, DEC, BIN, OCT)

The calculator supports calculations in different number bases: hexadecimal (HEX), decimal (DEC), binary (BIN), and octal (OCT). Use the dedicated keys for these operations, typically found above the number keys (e.g., →OCT, →PŘIHRÁŠKA, →DEC, →HEX).

5.2. Complex Number Calculations

To enter and perform calculations with complex numbers, switch to Complex Mode. Press CPLX to activate this mode. The display will show "CPLX".

Refer to the calculator's key markings for specific complex number operations (e.g., real and imaginary part extraction, argument, magnitude).

5.3. Statistics Functions

The calculator supports one-variable statistical calculations. To enter Statistics Mode, press STAT. The display will show "STAT".

Použijte DATOVÉ CD key to clear statistical data and the M+ key to input data points. Statistical results (mean, standard deviation, etc.) can be retrieved using specific function keys, often accessed via 2. F.

5.4. Paměťové funkce

The calculator has one independent memory. Use the following keys:

• M+: Přičte zobrazenou hodnotu do paměti.
• STO: Stores the displayed value into memory.
• RCL: Recalls the value from memory to the display.

6. Údržba a péče

6.1. Čištění

To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the casing nebo vnitřních součástí.

6.2. Skladování

When not in use, store the calculator in its protective hardcover to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.

7. Řešení problémů

7.1. Běžné problémy

• Kalkulačka se nezapne: Zkontrolujte instalaci baterií a ujistěte se, že nejsou vybité. V případě potřeby baterie vyměňte.
• "Error" message displayed: This usually indicates an invalid operation (e.g., division by zero, taking the square root of a negative number). Press CE or ON/C to clear the error and re-enter the calculation.
• Nesprávné výsledky: Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using ON/C než začnete nový.

7.2. Resetting the Calculator

If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the RESETOVAT button (a small recessed button, often requiring a thin object like a paperclip to press) on the back or front panel. Pressing this button will clear all memory and settings, returning the calculator to its factory default state.
